Description

Technical Field

[0001] The utility model belongs to the technical field of wire reels, and more specifically relates to a Thai large-current wire reel. Background Art

[0002] As Figure 5 shown, the original Thai large-current wire reel claims a maximum current of 16A, but most of them actually cannot pass the 16A temperature rise test, and most of them have a maximum current of only 13A. Because in order to pay attention to the symmetry of the internal electrical structure and reduce costs, the copper sheets used for internal conduction are made thin, so that customers use it as 16A when using it, which poses certain potential safety hazards. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a Thai large-current wire reel, which realizes the use of a maximum large current of 16A and improves safety.

[0004] To achieve the above object, the utility model provides the following technical solution: A Thai large-current wire reel includes a winding cylinder. An electrical structure is arranged inside the winding cylinder, and a socket panel is arranged at the end of the winding cylinder. The electrical structure includes a plurality of conductive copper sheets and a plurality of copper sheet brackets. The conductive copper sheets include a grounding conductive sheet and a live-neutral conductive sheet. A grounding socket is arranged on the grounding conductive sheet, and a plurality of live-neutral sockets are arranged on the live-neutral conductive sheet. Grounding jacks corresponding to the grounding sockets are arranged on the copper sheet brackets. It is characterized in that: the thickness of the conductive copper sheet is 0.8mm, the width of the conductive copper sheet is 5mm, four grounding sockets are arranged on the grounding conductive sheet, and the distance between each grounding socket and the adjacent two grounding sockets is 45mm. A first bending part and a second bending part are arranged on the grounding conductive sheet. The first bending part is an arc-shaped bending. The second bending part is 34mm away from the first bending part. The second bending part is Z-shaped. The top height of the second bending part is 12.5mm, the width of the second bending part is 4mm, and the middle section length of the second bending part is 8mm. The live-neutral conductive sheet includes a neutral conductive sheet and a live conductive sheet, and the neutral conductive sheet and the live conductive sheet are rotationally symmetric at 180 degrees. A concave section is arranged on the live-neutral conductive sheet.

[0005] Further, the electrical structure further includes an overload switch with a power indicator light, and the overload switch is located on one side of the copper sheet bracket.

[0006] Further, the width of the grounding jack is 10.4mm, and the distance between the side surface of the grounding socket and the inner wall of the grounding jack is 0.4mm.

[0007] Further, a temperature control switch is arranged between the several copper sheet brackets, and the distance between the center of the temperature control switch and the center of the socket panel is 7 mm.

[0008] Further, the live and neutral sockets include three plug clamping pieces, and the grounding socket includes two plug clamping pieces. Two of the live and neutral sockets and two of the plug clamping pieces in the grounding socket are inclined and close to each other. The inclination angle of the plug clamping pieces on the live and neutral conductive sheets is 70°, and the minimum distance between the ends of the two plug clamping pieces is 2.9 mm. The inclination angle of the plug clamping pieces on the grounding conductive sheet is 72.14°, and the minimum distance between the ends of the two plug clamping pieces is 2.7 mm. The third plug clamping piece in the live and neutral sockets is located on one side of the other two.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: by moving several jacks and the temperature control switch originally located at the center of the socket panel up by 7 mm, the position vacated below is replaced with an overload switch with a power indicator light, and the volume of the overload switch is larger than that of the prior art and can withstand a larger overload current. The thickness of all the internal conductive copper sheets is increased from 0.6 mm to 0.8 mm, and the width is increased from the original 4 mm to 5 mm, thereby increasing the current passing capacity of the conductive copper sheets, realizing the use of large current for the reel, and improving safety.
